Tungsten Carbide Button Optimization Profile

With the development of deep drilling and oilfield excavation, the performance of tungsten carbide button is also concerned. Most of profiles of tungsten carbide button are ball-shaped, and bullet-shaped. But it would be easily deactivate when we use the ball-shaped and the bullet-shaped would be vulnerable because of lackness of the matrix under a large impact. Based on the effective mechanism of spherical broken rock and bending stress curve theory, some researchers design blunt-resistant tungsten carbide button. It combines the advantages of the ball-shaped with the bullet-shaped, which is composed of two parts, a spherical cap and a cone. Spherical side is used in ball-shaped pressing die, and another approximate cone side is used in wedge pressing so that the effect of rock breaking is improved.
